Don't listen to this review, while bob is mostly right in his other reviews, he produced a very shallow perspective on this one.
The thing that is so great about this movie is that previous disney movies or princess movies are inherently flawed and naive. They always portrait the kingdoms the princess lived in were perfect with a wise king and kind followers, but we know in history and in reality that's not how things are. Human are greedy self serving bastards, it's a hard thing to admit but we are....which was shown in the first act of the movie. Maleficient wasn't portrait as a hero, or that the humans were the bad guys, the humans were just doing what human does in medieval era and she's just refused to be bullied and defended herself.
The kid she fell in love with didn't kill her and took her wings instead because even if his ambition is more important to him, she's still his childhood friend. Is it really so hard for bob to understand it isn't easy to kill someone you known all your life? And neither can she kill him because of the same reason?
The second act makes perfect sense too, when you spend enough time with someone, even if it's someone you don't initially liked, you will grow fond of them....and Maleficient spend 15-16 years with this child. Is it so hard to grasp that you can bond with someone after spending 15 years with them?
The redemption arc DOES work, Maleficient was portrait as good in the beginning, it is just what her boyfriend did to her that turned her dark, but transformation can go both ways, where her boyfriend turned her dark, the baby she cursed returned her back to the light. For someone who was inherently good, it isn't hard to believe that their experience can reawaken the good inside of them.
This movie isn't for kids, I'm not even sure it's for some adults, it's for someone that HAD a naive view of love and awaken from it. People who never been in love, had their hearts broken or still think that true love is between a man and a woman will not fathom this movie.
In addition, if you watch this movie with too much of a literal eye you wouldn't enjoy it much. Instead try to look at it as a metaphor or poetry.
The first act can be seen as someone falling in love and think the other person is the world, a lot of us have been there and can surly empathize.
Remember how our gf/bf want to breakup with us for whatever reasons but they don't want to hurt us too much because of guilt but it hurt no less after the fact? That's the act of her getting her wings torn.
We then brood and think that life isn't fair and how can the other person be such a ***** and feel that everything is fucked, that's the act of her going dark.
After awhile we find something or someone else to occupy our time, that's the princess arc, and eventually we get over our lost love, that's the "redemption" part but I see it more as self healing act or reawaken old qualities.
The most brilliant of it all is when we realized that there is more to "true love" than lush and infatuation between a man and a woman, and they portrait it perfectly in one act.
If you've been in love and had your heart broken and gained a new perspective on "love" after you gotten over it, then this movie is absolute poetry and it's BEAUTIFUL!
